A single-parent Chinese medicine doctor accidentally entered a mysterious sanatorium to save his terminally ill daughter, and discovered that the so-called holy product of health preservation was actually a living biological weapon. Medical accident files that have been sealed for 20 years reveal the horrifying experiment of the dean's team using patients to cultivate Ganoderma lucidum. The protagonist discovers that his daughter has been selected as a new generation host, and must crack the thousand-year pharmacopoeia code within 72 hours to prevent the mother body of Ganoderma lucidum from awakening. When destroying the mother's body will lead to the death of all symbionts, the ethical dilemma of whether to save the daughter or save the common people will push the story to the climax.
